First Look: Specialized Riprock Plus-Size Kids' Bike

It was just a matter of time until kids benefitted from the new plus-size tire platform. With the introduction of the new Specialized Riprock line with 2.8-inch wide Big Roller tires, that time is now. And kids’ bikes might be the best choice yet for plus-size tires: While obstacles like sticks, rocks, and ruts can unsettle a normal-width tire, they're often simply mowed over without any drama on higher-volume, lower-pressure plus-size tires. Braking and climbing traction is greatly enhanced too, thanks to the tire’s larger contact patch with the ground. Plus, all of these benefits come without the clumsy feel that can sometimes accompany fat bikes on dirt.

Specialized will offer the Riprock in four models: one with 20 inch diameter wheels and three with 24 inch-diameter wheels. All will feature a lightweight aluminum frame designed with extra-low standover height and suspension forks. Powerful disc brakes come on all models, as well as simple gripshift-equipped 1x drivetrains with wide-range cassettes.

The base-model Riprock 20 with small 20 inch-diameter wheels costs $450, while the larger 24-inch wheeled version will retail for $500. These two bikes have very similar spec with mechanical disc brakes, seven-speed drivetrains, and coil-sprung forks. The Riprock Comp 24 costs $750 and sees upgrades such as hydraulic Tektro Auriga disc brakes and a Shimano Alivio nine-speed drivetrain with wider range 11-36t cassette. At the top of the line is the Riprock Expert 24, which will likely share some components with Mom and Dad’s bikes. It’s outfitted with Shimano Deore hydraulic disc brakes and a 10-speed drivetrain with XT derailleur and 11-36t cassette. The Comp and Expert versions also get a fork upgrade with a lighter air spring and hydraulic lockout.

These bikes are unisex but are offered in a wide variety of colors to suit the tastes of almost any kid. All models started shipping to Specialized dealers this week—just in time for the gift-giving season.
